30Pcs Car Fender Clips Rivets & 1 pcs Manifold Absolute Pressure Sensor MAP sensor is a true absolute sensor, meaning it will enable your engine management system to properly compensate for altitude. The pressure inside your intake manifold is extremely important input to the ECU. A quality MAP sensor is crucial to your engines performance. These sensors will respond to changes in manifold pressures and relay the information to the ECU in the form of a voltage signal ranging. 3 bar MAP sensors precisely calculate boost pressure up to 43.5 psi gauge (58 psi absolute), while allowing you to have a smooth and repeatable idle. colour:black Plastic Rivets: Applications1:Defender Door Card Interior Weatherstrip Moulding Applications2:NYLON CHRISTMAS TREE Carpet Floor Mat Clips Rivet post pressure expands legs for fast and permanent fastening. 2.Used widely for car fender, bumper, door or other car suface.
